NCBI Protein Information
adenine phosphoribosyl transferase 2
NCBI Summary
Encodes an adenosine phosphoribosyl transferase(E.C:2.4.2.7), a constitutively expressed enzyme involved in the one-step salvage of adenine to AMP. This isozyme has high affinity for cytokinins and is likely to be localized to the cytosol.

UniProt Comments
Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. May contribute to the recycling of adenine into adenylate nucleotides and the inactivation of cytokinins by phosphoribosylation. Possesses low activity toward adenine and cytokinins.
